UNITED SAM MEYER, OF ST. LOUIS, MISSOURI.

VENTILATOR FOR SHOW-WINDOWS.

Application filed October 22, 1918.

To all whom it may concern:

Be it known that I, SAM MEYER, a citizen of the United States residingat the city of St. Louis, State of Missouri, have invented a certain newand useful Improvement in Ventilators for Show-Hndows, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part thereof.

This invention relates to a certain new and useful improvement inventilators for show or display-windows.

In modern merchandising establishments, for the purpose of displayingmerchandise to, and thereby attracting the patronage of, pedestriansupon the street, portions of the lower floor space at the front of thebuilding are generally partitioned off from the interior fioor space andbuilt or provided upon the street side with transparent glass affordinga view into the show or display window. In cold or wintry weatherparticularly, due to the difference in temperature between the outsideatmosphere and the interior of the show-window, the glass frequentlybecomes frosted, the view into the show-window being thereby obstructedor impeded and the purpose of the showwindow being thus neutralized. Toobviate the View of pedestrians into the show-window being soobstructed, is the chief object of my present invention; and with thisobject in view, my present invention resides in the provision of certainnovel and efficientventilating-members adapted to be arranged or builtin the window both above and below the glass front of the window wherebycold air from the exterior may be permitted to find passage into theshow-window and a circulation of air in the show-window be produced, theinner surface of the glass front being thereby maintained at relativelyas low a temperature as the outer surface of the glass front andfrosting thereof consequently prevented, and in certain novel featuresof form, construction, arrangement, and combination of parts, all aswill hereinafter be described and afterward pointed out in the claims.

In the accompanying drawings,

transom-bar of the show-window, showing the outer screened end of theupper ventilatlug-member Fig. 3 is a fragmental plan view of the floorof the show-window, showing the inner end of the lowerventilating-member;

Fig. l is a longitudinal sectional view taken approximately on the line4-4;, Fig. 3; and

Figs. 5 and 6 are enlarged perspective views of a pair of theventilating-members Referring more particularly to the said drawings, inwhich like reference characters refer to like parts throughout theseveral views, 1 indicates the sill, 2 the store-front, 3 thetransom-bar, a the floor, 5 the ceiling, 6 the cellar-bulkhead, and 7the windowglass of a show-window of usual or general construction.

The upper ventilating-member A, which is a rectangular hollow metallicshell open at its inner and outer ends, as at 8 and 9, respectively, ismounted flatwise in the tran som-bar 3, as shown, with its inner end 8presented toward and communicating with the interior of the show-windowand its outer end 9 presented toward the exterior of the building andcommunicating preferably with atmosphere. At its outer end 9, the upperand lower walls of member A are preferably flanged or bent inwardly uponthemselves, as at 10l0, to provide a neat finish; and fixed flatwiseupon the outer surface of transom-bar 3 and over the outer end 9 of themember A, and in a large measure preventing the entrance ofdust-particles and the like from the exterior into the member A. is aperforated face-plate 11. At its inner end 8, the upper and lower Wallsof member A are oppositely bent or flanged outwardly to provide tracksor ways 12-12 for a pair of oppositely disposed independentinner-end-closing slides 13-l3, each of which is flanged at its sides,as at 141l l, into sliding engagement with the tracks or ways 12. Theslides 13 are of a combined length substantially equal to the length ofthe open end of the ventilator and are independently movable toward andaway from each other, by which arrangement it is possible to adjust theslides to afford an opening of any desired area and at any desired pointbetween the ends of the opening in the shell. Adjacent its inner end,each slide 13 is provided with an inwardly disposed stud or pin 15adapted to engage a side wall of the member A to limit the openingmovement of the slide.

The lower ventilating-member B, which is a hollow metallic shell made uppreferably integrally of two communicating portions or legs 1617disposed at right angles one to the other, the shell B being similarlyopen at its inner and outer ends, as at 18 and 19, respectively, ismounted in the show-window with its somewhat longer leg 17 disposedapproximately flatwise beneath the sill 1 with its end 19 presentedtoward the exterior of the building and communicating with atmosphere.The other leg 16 of shell B is disposed approximately vertically betweenthe fioor 4: and inner face of the sill 1, as shown, its open end 18being presented toward and communicating with the interior of theshow-window closely adjacent the inner face of the glass 7. At its outerend 19, which projects slightly beyond the plane of the front 2, theupper and lower walls of shell or member B are also oppositely bent orflanged outwardly to provide tracks or ways 20-20 for a pair ofoppositely disposed closing-slides 2121, each of which is similarly bentat its sides, as at 22, into sliding engagement with the tracks or ways20. At its inner end 18, which projects slightly above the plane of thefloor 4, the shell B is likewise and similarly provided with tracks orways 23-23 for a pair of similar closing slides 24l--24 similar inconstruction and operation to the slides 13 of the upper member, and ashereinbefore described; and surrounding the inner end 18 of the shell Band screwed or otherwise fixed to the floor 4,is a plate 25 adapted notonly to provide a neat trim for the inner end of the shell B within theshow-window, but also a smooth surface upon the floor 4 for the slides2424 in opening and closing. Each slide 21 and 24 is likewise providedwith a stud or pin 26 adapted to engage a side wall of the shell ormember B to limit the opening movement of the particular slide.

In warm weather, the several slides are usually closed. In cold orwintry weather, or whenever it is desired to regulate the temperature ofthe show-window relatively to the temperature of the outside atmosphere,the several slides are suitably manipulated to open position, when, aswill be evident, cold air from the outside will flow through the lowerventilating-member or shell B into the show-window closely adjacent theglass 7. The entering cold air will strike the inner surface of theglass 7 and circulate more or less within the show-window, the warmerair finding exit to atmosphere through the upper ventilating-menber orshell A. The temperature within the show-window will soon approximatethe temperature of the outside atmosphere, and

consequently view-obstructing frosting of the glass 7 will be obviated.It will be understood that, while I have shown but one pair of theventilating-members A and B, the show-window will be equipped with anydesirable number of said members suitably disposed in properly spacedrelation above and below the glass 7, as described.

In the installation of my ventilator system, the upper and lowerventilating members are preferably located one above the other or insubstantial vertical alinement, and by the provision of the twoindependently movable slide members at the openings in the respectiveventilator members, it is possible to adjust the slides to affordopenings in the respective members of the same or different areas andalso to position the openings in the respective members into or out ofvertical alinement, as conditions may require or make it necessary toprovide proper ventilation.

My new show-window ventilating-members A and B may be economically andcheaply manufactured and conveniently operatively installed and mountedin connection with the show-window, each member B being preferablyrigidly fixed in position by means of one or more securing screws or thelike 27 projected therethrough and into a filler-block 28 disposedbeneath and, in turn, fixed to the sill 1.

I am aware that minor changes in the form, construction, arrangement,and combination of the several parts of my new show-window ventilatorsmay be made and substituted for those herein shown and described withoutdeparting from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A show window ventilator, comprising a rectangular shell of extendedwidth open at its ends and adapted to be fixed in the wall of a windowand affording communication between the outside atmosphere and theinterior of said window, and a pair of independent slides mounted uponthe open end of said shell and of a combined length substantially equalto the length of the opening and adapted to be independently adjusted toafford openings of different area and at any desired point between theends of the opening in the shell.

2. A show window ventilator, comprising a rectangular shell of extendedwidth open at its ends and adapted to be fixed in the wall of a windowand affording communication between the outside air and the interior ofsaid window, a pair of independent slides mounted upon the said open endof said shell and of a combined length substantially equal to the lengthof the opening and adapted to be independently adjusted to affordopenings of different area and at any desired point between the ends ofthe opening in the shell, and stops on said slides for limiting theopening movement of the slides.

8. The combination with a. show window including a pane of glass and aframe therefor mounted in a wall, of an injector ventilator comprising aright-angled shell open at its ends adapted to be permanently mounted inthe wall and located below and adjacent to and along the inner side ofthe sill of the window frame for directing the air inwardly and upwardlythrough said injector ventilator and along the glass of said window anejector ventilator comprising a straight rectangular shell open at itsends and adapted to be permanently mounted in the upper rail of saidwindow frame in substantial vertical alinement with the injectorventilator, and means for controlling the passage of air through saidinjector and ejector ventilators, comprising a pair of independentslides fitted to the open ends of said ventilators and adapted to beindependently adjusted to afford openings in the respective ventilatorsof the same or different areas and at the same or different positions inthe respective ventilators.

In testimony whereof I have si ned my name to this specification.

SAM MEYER.
